偶氮胂 应用于稀土总量的测定早有报道[1] ,但作者在应用这些方法分析高铝矿时 ,发现铝有严重干扰 ,且灵敏度不高 ,本文采用 1 -苯基 - 3-甲基 -4-苯甲酰基代吡唑酮 ( PMBP)萃取分离。经 8-羟基喹啉 -甲酸反萃后于水相中 [2 ]进行偶氮胂 ( ) ( Ars( ) ) -溴化十六烷基三甲基 Arsenazo used in the determination of the total amount of rare earth has been reported [1], but the author in the application of these methods analysis of high-aluminum, found that aluminum has a serious interference, and the sensitivity is not high, this paper 1-phenyl-3- 4-benzoylpyrazolone (PMBP) extraction. Arsenazo () (Ars ()) - cetyltrimethylammonium bromide (8-hydroxyquinoline-formic acid)
